-ATTURNE Y ALEXANDER GIRTANNER, OF NEW YORK, N. Y.

ASH-CONVEYER.

Specification of Letters Patent.

Patented July 20, 1920.

Application filed April 16, 1919. Serial No. 290,546.`

T0 all whom t may concern:

Be it known that I, ALEXANDER GIRTAN- NER, a citizen of the United States of America, residing at the city of New York, State of New York, have invented a certain new and useful Ash-Conveyer, of which the following is such a full, clear, and exact description as will enable anyone skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to an ash conveyer and more particularly to means for providing a removable lining for the horizontal portion of the conveyer.

In the accompanying drawings which illustrate one form of ash conveyer made in accordance with my invention, Figure 1 is a vertical longitudinal section, Fig. 2 is a top plan view and Fig. 3 is an enlarged section taken on the line 3-3 of Fig. 1.

The conveyer consists of a horizontal ortion 5 and a vertical portion 6 connecte by an elbow 7 carrying a blast nozzle 8 for forcing the material through the conveyer in the direction indicated by the arrows in Fig. 1 of the drawings. The horizontal portion 5 of the conveyer consists of a number of sections 9 which may be secured together in any suitable manner; as for instance by means of bolts 10 passing through flanges 11 on the various sections. One of the sections 9 is provided with an upwardly extending portion 12 having secured to 1t a plate 13 for allowing the removal and insertion of the lining. This plate 13 is also preferably provided with an ash inlet opening 14 closed by a cover 15.

The lining consists of a number of sections 16 which are so arranged in the conveyer as to break joints with the sections of the latter. Each section of the lining 16 has the curvature of its lower face 17 formed on a radius somewhat greater than the radius of curvature of the interior face of the section 9, as best shown in Fig. 3 of the drawings. This holds jthe central part of the lining out of contact with the bottom of the conveyer tube and consequently insures tight contact of the edges of the lining with the walls of the conveyer and thus prevents access of ashes to the space between the lining and conveyer. Each section of the lining is also provided at each end with ra beveled face 18 so that the abutting ends of the lining when placed together form overlapping joints inclined to the direction of travel of the material in the conveyer tube. The elbow 7 is preferably provided with a lbeveled shoulder 19 for engaging with the beveled end 18 of the forward lining section 16.

It will be evident that by my construction I secure a lining which effectively protects the bottom of the conveyer tube from wear and that the lining can be readily renewed.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

l. In an ash conveyer, the combination with a tubular member formed in sections, of a sectional lining covering the lower inner surface of said tubular member, one of the sections of said tubular member being provided with an opening for the insertion and removal of the lining, a plate closing said opening, and an ash inlet in said plate.

2. In an ash conveyer, the combination with a tubular member of a removable lining covering the lower inner surface of said tubular member and held therein b gravity, the curvature of the lower face o said lining being of greater radius than that of the adjacent wall of the tubular member and contacting therewith at its edges only whereby contact is secured between the edges of the lining and the tubular member without fastening means.

In testimony whereof, I have hereunto set my hand and affixed my seal April 9, 1919.

ALEXANDER GIRTNNER. [1.. 8.]
